VI - THE VICTROLA TUNGS-TONE STYLUS
AND THE VICTOR STEEL NEEDLE
We recommend that in playing your records you always use the Victrola Tungs-tone stylus, because it is the one ideal reproducing point. The Tungs-tone stylus employs the metal tungsten, which is soft and fibrous, not hard and crystalline. The Victory Company controls by patent, the use of this metal for reproducing points, and
while other points have been made imitating the general form of tungs-tone styli, they are invariably of some other material. The Tungs-tone stylus, because of its soft texture will not wear out your records. And it does not have to be changed for each record. Instead of being tapered the Tungs-tone stylus is cylindrical inn shape, and of the same width as the record groove. As its tip wears down, the stylus will not, therefore, like a tapered point, tend to crowd the sides of the record groove and thus impair the tone of the music. Its diameter remains the same from first to last. Each Tungs-tone stylus should play from 100 to 300 records. It is desirable to occasionally give the stylus a partial turn in the needle arm.
The Victor steel needles are made with the utmost care, and each and every one is polished to a spherical point and fits perfectly in the Victor record grooves.
If you’re going to use a Tungs-tone needle, play only on Victor Tungs-tone records.
Cool! Not directly stated, but seems to describe the Tungsten-Copper alloy.
